I really like it so far. the auto-mapping is a very nice touch, and the characters are all really likeable. The first stratum looks fantastic,
and the music is just sooooo smooth. It's also fixes the problems of the first game, like not being able to shift through your party to check their equipment and not getting EXP from doing requests.
It's not all a basket of roses though, as the plot is kinda shaky. I'm hopeful that it will get better as it progresses; after all, it is a demo. I'm also not quite grasping the concept of the Grimoire Stones and Chances, but I figure it'll be something that will be mastered in time.
Now with all that all being said, I freaking love the description for Expert mode. "This setting is for true masters of the Etrian series, or masochists." Shine on, Atlus. Shine on. :'D
